Description
Anordnung zur Anschaltung eines Verbrauchers für Hochfrequenz an eine Hochfrequenzquelle In dem Hauptpatent 522 682 ist eine Anordnung von Antennen an Hochfrequenzquellen unter Benutzung von Energieleitungen beschrieben, welche eine gute Anpassung des Wellenwiderstandes bzw. Strahlungswiderstandes der Antenne an die Energieleitung gewährleistet. Es wird zu diesem Zwecke als Energieleitung ein Doppeldrahtsystem verwendet, bei welchem die Antenne, die wie eine Impedanz wirkt, an den einen der beiden Leiter gelegt ist, während der andere Leiter über eine Ersatzkapazität, die gleich der Antennenkapazität ist, geerdet wird.Arrangement for connecting a consumer for high frequency to a Radio frequency source In the main patent 522,682 an arrangement of antennas is on High frequency sources using power lines described which a good adaptation of the wave resistance or radiation resistance of the antenna the power line is guaranteed. It is used for this purpose as an energy conduit Two-wire system used in which the antenna, which acts like an impedance, is connected to one of the two conductors, while the other conductor has an equivalent capacitance, which is equal to the antenna capacity, is grounded.
Vorliegender Erfindung gemäß wird diese Ersatzkapazität in besonders einfacher Weise in Form eines Leiters von so großer linearer Ausdehnung ausgeführt, daß auf ihm stehende Wellen entstehen.According to the present invention, this substitute capacity becomes particularly simply designed in the form of a conductor of such a large linear dimension, that standing waves arise on it.
In der in der Abb. i gezeigten Anordnung besteht die Ersatzkapazität aus dem Draht A B, der am Ende geerdet, isoliert usw. sein kann, und dessen Länge so gewählt ist, daß die Impedanz des Stückes A B im Punkte A gleich der Antennenimpedanz im Punkte A' ist. Eine absolute Abgleichung der beiden Impedanzen ließe sich allerdings in diesem Falle nur auf Kosten der durch die Antenne ausgestrahlten Leistung erreichen, weil dann der Leiter A B ebensoviel Energie verbrauchen würde als die Antenne.In the arrangement shown in Fig. I, the equivalent capacitance consists of the wire A B, which at the end can be earthed, insulated, etc., and the length of which is chosen so that the impedance of the piece AB at point A is equal to the antenna impedance at point A 'is. In this case, however, an absolute matching of the two impedances could only be achieved at the expense of the power emitted by the antenna, because the conductor AB would then consume as much energy as the antenna.
In der in der Abb. i dargestellten Schaltung entsteht durch den plötzlichen Übergang der Antenne auf die Doppeldrahtleitung eine Reflexion der Welle, die stehende Wellen auf der Leitung und dadurch hohe Spannungen und Energieverluste verursacht. Diese Reflexion wird geringer, wenn der Übergang von Antenne auf Energieleitung kontinuierlich gemacht wird.In the circuit shown in Fig. I, the sudden Transition of the antenna to the two-wire line a reflection of the wave, the standing one Waves on the line, causing high voltages and energy losses. This reflection is less when the transition from antenna to power line is done continuously.
Abb.2 zeigt ein Ausführungsbeispiel einer Kurzwellenantenne, bei dem der Wellenwiderstand der Energieleitung über eine Strecke, deren Länge mit ?t vergleichbar ist, sich kontinuierlich ändert zwischen dem Wellenwiderstand der Antenne und dem Wellenwiderstand der Leitung.Fig.2 shows an embodiment of a shortwave antenna in which the wave resistance of the power line over a distance whose length is comparable to? t is, changes continuously between the wave impedance of the antenna and the Characteristic impedance of the line.
